Abstract:In order to improve the accuracy of fault diagnosis of the wind turbine's pitch system, an improved stack autoencoder network is proposed. Based on the Supervisory Control And Data Acquisition (SCADA) data of the wind turbine's electric pitch system, the batch normalization (BN) algorithm was introduced for the gradient dispersion problem in the feature extraction of ordinary autoencoder networks when there are many parameters. This article uses the Adam optimizer to iteratively update the neural network weigh… Show more
